This is direct from the Devon C2 Manual and may not be a lot of use,. The Datum is indicated by a plate on the port side of the fuselage 2.60 feet aft of the forward levelling peg.

Forward Limit:

(Item 1) At 9150 lbs - 2.46 inches Forward of Datum

(Item 2) Up to 8625 lbs - 3.70 Inches Forward of Datum

A note for for Item 1 and 2 says Varies linearly for intermediate wheights.

Aft Limit - 7.20 Inches aft of Datum

To keep within the above limitations it may be necessary to carry ballast and to limit the passenger/fuel carried.

Sorry it is the only information in the Devon C 2 Aircrew Manual. Ian Br

Thanks Ian,

It would be enough if we knew where the datum was. It's academic really as what counts in FSX is how the CG is defined in the aircraft.cfg file. In this case the datum is at the default position for FSX (25% MAC) and the load station positions seem reasonable.

Just completed a short Circuit, removed baggage and all passengers, she seemed much improved on the handling side and also was able to use full flaps for the arrival. It may well be that the cg for some reason is moving too far aft. I shall try a few more flights over the weekend putting passengers back on board which should move it back aft. Of course when I was having problems I may have been mishandling her. Still like her though.

I too think it's a CG problem, as when unloaded she handles nicely without any trim or control issues.

Seems the load is too far aft, even when under gross weight. Makes the Dove fly very unstable.

Not sure where to share this so support sees it, but definitely seems like the problem.

Also, over on AVSIM it was noted that the startup engine sounds are missing... they are referenced in the sound cfg file, but don't actually get installed in the released version.

Great plane though! Thanks JF!

Unloading the plane might make it easier to fly, but it's still longitudinally unstable with the CG as far forward as it will go. That should not be the case and it indicates a problem with the AIR file.

Edit 1:

I've just had a look in the AIR file and table 473 (CM v AOA) is missing. That could explain a lot.

Edit 2:

I experimentally added table 473 to the Dove AIR file, copied and pasted from the default DC-3 AIR file. A quick flight test shows this makes the Dove stable in pitch (it tries to return to the trimmed speed if disturbed). It should improve handling a lot. This is a rough and ready solution, but it works.

Thanks for this. I tried it myself and it certainly makes for a more flyable plane, though whether its more realistic, I couldn't say.

Just a quick note about the Dove - thanks to all who have purchased it. We are indeed working on a service pack to address the reported issues. Thanks to everyone who has sent their feedback to us and we hope to have news on the service pack soon.

I'm glad I spotted your post. I'm experiencing the same issues in P3D v3. It is hell to control, changing pitch simply at random almost. Straight and level is almost impossible. The biggest problem is takeoff - with or without flaps - it simply climbs at an ever increasing angle and into a stall unless I push well forward with the yoke; then, suddenly, it seems to relax the required amount of initial forward pressure.Agree on the paint jobs too. At first I thought it was my settings given some of the screenshots in the advertising material and manual;but, no, it's the Dove's lack of reflection.Hoping for an update soon as it's not really making me happy yet, despite loving the modelling.

I submitted a support ticket a few days ago but have had no response or acknowledgement yet. In case it's not been received here are my notes as I made them, just for the record:

Manual:I'm confused about the different versions: the Mk2 has a transparent cockpit roof and cockscomb aerial. The BOAC version has these features but is described as an early Mk 6 on p8 under Liveries and on p62 in the tutorial and in the aircraft selection list in P3D.

Flying the Dove in P3D v2.5:Elevator trim setting for take-off: I crashed the first two times on climb-out (!) because the trim was at 0 as I was following the checklist in the manual. I have found it needs to be at least around minus 4 to 5 to stop the aircraft stalling.

As others have found, it's generally unstable in pitch. It is very difficult to trim for straight and level flight. I have slightly improved this by increasing Elevator effectiveness and Pitch Stability in the aircraft.cfg file to 2.0.

The Dove gains and loses airspeed very quickly when climbing and descending, and with full flap on the approach: is this a feature of the actual aircraft?

Sound:Missing engine start-up sound. As others have suggested, I corrected this by adding freeware sounds and renaming them.

Cruise sound:While flying in the vc, if I go to exterior view and then back to the vc, the engine sound has completely changed (corrected if throttles are moved a fraction).

I'm wondering how these things were missed in all the beta testing that must have been done!

When you submit a ticket you should receive an acknowledgement email almost immediately. Are you saying you've not seen that reply also?
